Noise And Vibration; Test Report - nifty Mk 3 Seies Operating/Safety Instructions Manual

Height Rider/SP Series
Operating & Safety Instructions
2.3

NOISE AND VIBRATION

The airborne noise emission on the Height Rider range of machines does not exceed 79dB(A),
measured at a perpendicular distance of 4m, under equivalent continuous A-weighted sound pressure
test conditions. This was based on a diesel powered machine working on high throttle and under load.
All other models will exhibit significantly lower emissions than this figure, dependant on power option.
In normal operation the vibration level to which the operator is subjected will not exceed a weighted
root mean square acceleration value of 2.5 m/s².

TEST REPORT

All Niftylift machine models are subjected to a comprehensive 'type test' which duplicates all
combinations of safe working load (SWL), overload, windage, inertia, and pull force to assess the
various safe stability criteria. Self-propelled machines are also subjected to kerb and braking tests at
the SWL to satisfy additional 'worst case' stability requirements.
Each individual machine is then subjected to static overload tests on flat level ground with 150% of the
SWL, exceeding the requirements of EN280 for power operated MEWPs. Self-propelled machines are
also tested at the maximum working angle plus 0.5° with a test load of 125% of the SWL. Finally, on all
machines, a functional test is performed with 110% of SWL.
All safety devices are checked for correct operation, operating speeds are checked against benchmark
figures, and the dynamic functions are checked to ensure that all acceleration and deceleration forces
are within acceptable limits. All noted defects are rectified and recorded before the machine is
permitted to enter into service.
